I connected with the language confusion piece. I used to teach English Language Learners, mostly students who came to the US from Mexico. I remember one young lady who had not learned her native language well enough to be able to connect it to English words to be able to learn in either language. It's called language confusion and it's so hard to work through! They say the key to fixing language confusion is to work on the native language so that they have the word bank and experiences to then connect to a second language. If they are understanding you when you speak your native language, then hopefully speaking is next for them! It can take many years (3-5) to learn to speak socially and then even more time to learn to speak academically.
